The new css layout pdf download
This article will recap some of the CSS layout features we've already touched upon in previous modules — such as different display values — and introduce some of the concepts we'll be covering throughout this module. The page layout techniques we'll be covering in more detail in this module are. Each technique has its uses, advantages, and disadvantages, and no technique is designed to be used in isolation.
By understanding what each method is designed for you will be in a good place to understand which is the best layout tool for each task. Let's look at a quick HTML example:. Note here how the HTML is displayed in the exact order in which it appears in the source code, with elements stacked up on top of one another — the first paragraph, followed by the unordered list, followed by the second paragraph. The elements that appear one below the other are described as block elements, in contrast to inline elements, which appear one beside the other, like the individual words in a paragraph.
Note : The direction in which block element contents are laid out is described as the Block Direction. The Block Direction runs vertically in a language such as English, which has a horizontal writing mode.
The corresponding Inline Direction is the direction in which inline contents such as a sentence would run. This is why starting with a well-structured HTML document is so important, as you can then work with the way things are laid out by default rather than fighting against it. The main methods of achieving page layout in CSS are all values of the display property. This property allows us to change the default way something displays.
Everything in normal flow has a value of displayused as the default way that elements they are set on behave. For example, the fact that paragraphs in English display one below the other is due to the fact that they are styled with display: block.
This is because the element or anchor elementwith its href attribute, creates a hyperlink to web pages, files, email addresses, locations in the same page, or anything else a URL can address. You can change this default display behavior. For example, the element is used to represent an item in a list.
If we change the display value to inline they now display next to each other, as words would do in a sentence, the new css layout pdf download. The fact that you can change the value of display for any element means that you can pick HTML elements for their semantic meaning, without being concerned about how they will look.
The way they look is something that you can change, the new css layout pdf download. In addition to being able to change the default presentation by turning an item from block to inline and vice versa, there are some bigger layout methods that start out as a value of display.
However, when using these, you will generally need to invoke additional properties. The two values most important for our purposes when discussing layout are display: flex and display: grid. Flexbox is the short name for the Flexible Box Layout Module, designed to make it easy for us to lay things out in one dimension — either as a row or as a column. To use flexbox, you apply display: flex to the parent element of the elements you want to lay out; all its direct children then become flex items.
We can see this in a simple example. The HTML markup below gives us a containing element, with a class of wrapperinside which are three is the the new css layout pdf download container for flow content.
It has no effect on the content or layout until styled using CSS. By default these would display as block elements, below one another, in our English language document. However, if we add display: flex to the parent, the three items now arrange themselves into columns.
This is due to them becoming flex items and being affected by some initial values that flexbox sets on the flex container. They are displayed in a row, because the initial value of flex-direction set on their parent is row. They all appear to stretch to the height of the tallest item, because the initial value of the align-items property set on their parent is stretch. This means that the items stretch to the height of the flex container, which in this case is defined by the tallest item.
The items all line up at the start of the container, leaving any extra space at the end of the row. In addition to the above properties that can be applied to the flex container, there are properties that can be applied to the flex items. These properties, among other things, can change the way that the items flex, enabling them to expand and contract to fit into the available space.
As a simple example of this, we can add the flex property to all of our child items, with a value of 1. This will cause all of the items the new css layout pdf download grow and fill the container, rather than leaving space at the end. If there is more space then the items will become wider; if there is less space they will become narrower. In addition, if you add another element to the markup the items will all become smaller to make space for it — they will adjust size to take up the same amount of space, whatever that is.
While flexbox is designed for one-dimensional layout, Grid Layout is designed for two dimensions — lining things up in rows and columns, the new css layout pdf download. Once again, you can switch on Grid Layout with a specific value of display — display: grid.
The below example uses similar markup to the flex example, with a container and some child elements. In addition to using display: gridwe are also defining some row and column tracks on the parent using the grid-template-rows and grid-template-columns properties respectively.
We've defined three columns each of 1fr and two rows of px. Once you have a grid, you can explicitly place your items on it, rather than relying on the auto-placement behavior seen above. In the second example below we have defined the same grid, but this time with three child items.
We've set the start and end line of each item using the grid-column and grid-row properties. This causes the items to span multiple tracks. Note : These two examples are just a small part of the power of Grid layout; to find out more see our Grid Layout article. The rest of this guide covers other layout methods, which are less important for the main layout structures the new css layout pdf download your page but can still help you achieve specific tasks.
By understanding the nature of each layout task, you will soon find that when you look at a particular component of your design the type of layout best suited to it will often be clear. Floating an element changes the behavior of that element and the block level elements that follow it in normal flow.
The element is moved to the left or right and removed from normal flow, and the surrounding content floats around the floated item. The float property has four possible values:.
This gives us the effect of text wrapped around that box, and is most of what you need to know about floats as used in modern web design. Note : Floats are fully explained in our lesson on the float and clear properties, the new css layout pdf download. Prior to techniques such as Flexbox and Grid Layout floats were used as a method of creating column layouts. You may still come across these methods on the web; we will cover these in the lesson on legacy layout methods.
Positioning allows you to move an element from where it would be placed when in normal flow to another location. There are however useful techniques for certain layout patterns that rely on the position property. Understanding positioning also helps in understanding normal flow, and what it is to move an item out of normal flow.
To provide familiarity with these page layout techniques, we'll show you a couple of quick examples. Our examples will all feature the same HTML, which is as follows:. Relative positioning allows you to offset an item from the position in normal flow it would have by default. This means you could achieve a task such as moving an icon down a bit so it lines up with a text label.
To do this, we could add the following rule to add relative positioning:, the new css layout pdf download. Here we give our middle paragraph a position value of relative — this doesn't do anything on its own, so we also add top and left properties.
These serve to move the affected element down and to the right — this might seem like the opposite of what you were expecting, but you need to think of it as the element being pushed on its left and top sides, which result in it moving right and down. Absolute positioning is used to completely remove an element from normal flow, and place it using offsets from the edges of a containing block.
Going back to our original non-positioned example, we could add the following CSS rule to implement the new css layout pdf download positioning:. Here we the new css layout pdf download our middle paragraph a position value of absoluteand the same top and left properties as before. Adding this code, however, will give the following result:. This is very different! The positioned element has now been completely separated from the rest of the page layout and sits over the top of it.
The other two paragraphs now sit together as if their positioned sibling doesn't exist. The top and left properties have a different effect on absolutely positioned elements than they do on relatively positioned elements. In this case the offsets have been calculated from the top and left of the page. It is possible to change the parent element that becomes this container and we will take a look at that in the lesson on positioning. Fixed positioning removes our element from document flow in the same way as absolute positioning.
However, instead of the offsets being applied from the container, they are applied from the viewport. As the item remains fixed in relation to the viewport we can create effects such as a menu which remains fixed as the page scrolls beneath it. For this example the new css layout pdf download HTML is three paragraphs of text, in order that we can cause the page to scroll, the new css layout pdf download, and a box to which we will give position: fixed.
Sticky the new css layout pdf download is the final positioning method that we have at our disposal. It mixes the default static positioning with fixed positioning. When an item has position: sticky it will scroll in normal flow until it hits offsets from the viewport that we have defined. At that point it becomes "stuck" as if it had position: fixed applied.
Note : to find more out about positioning, see our Positioning article. HTML tables are fine for displaying tabular data, but many years ago — before even basic CSS was supported reliably across browsers — web developers used to also use tables for entire web page layouts — putting their headers, footers, different columns, etc. This worked at the time, but it has many problems — table layouts are inflexible, very heavy on markup, difficult to debug, and semantically wrong e.
The way that a table looks on a webpage when you use table markup is due to a set of CSS properties that define table layout. These properties can be used to lay out elements that are not tables, a use which is sometimes described as "using CSS tables". The example below shows one such use; using CSS tables for layout should be considered a legacy method the new css layout pdf download this point, for those situations where you have very old browsers without support for Flexbox or Grid.
Let's look at an example. First, some simple markup that creates an HTML form. Each input element has a label, and we've also included a caption inside a paragraph, the new css layout pdf download. Now, the CSS for our example, the new css layout pdf download.
